广州某公建项目地下空间室内通风模拟优化分析

Simulation and optimization analysis of indoor ventilation for an underground space in a public construction project in Guangzhou

良好的地下空间通风效果可以改善室内环境,调节热湿环境,提高室内空气质量,为使用者提供健康舒适的休闲娱乐空间。以广州某公共建筑作为研究对象,结合室外场地风压计算结果,通过优化天井位置及尺寸,利用Airpak软件模拟计算各工况的风速、换气次数,对结果进行对比分析。结果表明,通过调整通风口位置、尺寸、组合方式,可以有效改善室内通风状况。

Good ventilation in underground spaces can improve the indoor environment,regulate the thermal and humidity conditions,and enhance the air quality,providing users with a healthy and comfortable space for leisure and entertainment.Taking a public construction project in Guangzhou as the research object,combined with the results of outdoor site wind pressure calculations,the positions and sizes of the courtyards are optimized.Using the Airpak software,the wind speed and air change rates under various conditions are simulated and calculated.The results show that by adjusting the positions,sizes,and combinations of ventilation openings,the indoor ventilation conditions can be effectively improved.
